Many Comic-Con fans might be disappointed that they couldn’t nab the 1,000 four-day badges that went on sale Wednesday as part of a test, but organizers are pleased they didn’t have to shut down the online sales operation for a third time.

Deluged with a huge volume of aspiring purchasers, Comic-Con’s online system was able to process the sale of 1,000 badges to its four-day convention within 15 minutes, said spokesman David Glanzer.

The test sale was limited to just 1,000 passes for an event that normally draws more than 125,000 attendees. Comic-Con International set up the sale as a test to determine whether it will be able to accommodate the tens of thousands of people who want to buy passes without overloading computer servers.

Comic-Con tried twice in November to sell single-day and four-day passes to its pop culture extravaganza, but each time, the sale had to be halted after servers were overloaded, and purchasers were greeted with error messages.

“There was a tremendous amount of volume,” Glanzer said of Wednesday’s morning test. “We’ll be getting data soon and will spend the next two weeks poring over this to make it more efficient.

“We found people were utilizing several different browsers trying to access the site, so that may be the reason why we were having trouble before.”

He said that more than 500 badges were sold within the first two minutes, and within 15 minutes, the sale had ended.

Glanzer said the organization is hoping to announce a new sale early in the year.

“I’m cautiously optimistic,” he said. “There are still a few bugs, so we hope that when we announce our new registration dates, things will go smoothly.”

While Wednesday’s trial run succeeded, that didn’t stop frustrated fans from venting on Twitter. Some complained about “gateway errors” and a crashed server.

“When you gonna pay people back for all the wasted time, work hours, stress?” wondered one poster.

Glanzer acknowledged there were some glitches, but despite those, Comic-Con was able to process the sale of 1,000 badges.
